Titandioksid anodematerial for natriumionebatterier

Offentlig prosjektsammendrag

TioTech has developed TitanB, a novel titania anode material for Li-ion batteries (LIB). In this project, we are investigating the potential of using the TitanB in Na-ion batteries, which are a cheaper and more sustainable alternative to Li-ion batteries. While the supply and cost of lithium is a concern for the exponential growth of battery sales, sodium is a cheap and abundant material. The development of suitable anode materials remains a challenge though. Nanocrystalline titanium dioxide (TiO2) is a promising anode material in high-power, safe sodium ion batteries (SIBs) due to its structural stability, low cost, non-toxicity and good cycling performance. Preliminary testing of TioTechs titania in Na-ion batteries has revealed promising results and within this project, we are investigating this further. TioTechs titania will be integrated in coin-cell batteries and the corresponding battery chemistry will be investigated. A successful project includes demonstration in pouch cells.
